Reaction of (PPh3)3> (1) with CO in toluene at room temperature affords as one of the products the dinuclear complex syn-(CO)2(PPh3)2> (2).The crystal structure of (2) reveals it to be an unsaturated bimetallic species, with two Ru(CO)(PPh3) moieties bridged by an 8e^- donor η²-diimine ligand in a tetrahedral-like fashion and involving a triple Ru-Ru bond.
